Missing audio driver (Conexant HD Audio) from system device drivers, and unable to re-install driver.

    Question

  • I tried to look for a solution among the questions that were previously asked, but I could not find one. While  browsing the Internet my HP dv6636nr laptop all of  the sudden stopped responding, (firefox sometimes freezes then continues) and when it resumed I had lost sound. A new icon appeared that when moused over stated "No audio output device is installed".  I tried re-installing different versions of the driver, but nothing worked. I tried the HP recovery program - still nothing this same message appears: "Could not find the media device for this driver. I am a retired Computer Tech, but the solution to this problem eludes me. I'm using Vista Home O.S.  Any suggestions?
